A car starting from rest acquires a velocity $180 m s^{- 1}$ in $0.05 h$ .Find the acceleration

Open in App

Solution

Given,

Initial velocity $u = 180 m / s$
Time $t = 0.05 h = 0.05 \times 3600 s$
Assuming constant acceleration
$v = u + a t$
$\Rightarrow 180 = 0 + a (0.05 \times 3600) \Rightarrow a = 1 m / s^{2}$
